User reviews

Goes hard

Its good, just hope we will get a UZdoom port soon. At this moment though ProMotion is not available on the iOS version, iPadOS only (so youre stuck with 60fps for now)

Its good

I find it good Even I use it mostly for Doom mods nothing else

Yaaaaay doom I finally get to play brutal doom

Amazing

Its good but i have one issue

Make a option to disable dragging for all buttons because when im trying to select options and stuff the A button can press multiple times from one push and makes things tedious

Audio stopped working

Works great for a while then I bought the full version and the audio died.
